The conversion of hydroxyapatite to fluorapatite and the diffusion of fluoride into enamel from acidulated phosphate-fluoride solutions are both exothermic chemical processes. Thus, the postulate that these topical fluoride applications to enamel tend to form fluorapatite is sound thermodynamically.
